Purveyor of email etiquette Merlin Mann has made a list of 5 email tics we should all lose:

1. The liberal use of the VERY HIGH PRIORITY!!! flag
2. The 18-line sig about all the Bad Things that will happen to me if I ever reveal the contents of your privileged, confidential (and unencrypted) message
3. The unrequested press release (and the serial ignoring of the Unsubscribe I sent you for the previous seven press releases)
4. The graphical background, font and table tags, and remaining 14k of HTML cruft associated with every. single. message. you ve ever sent.
5. The including of my — plus 98 other strangers personal email addresses in the "To:" line of your friendly reminder about Tyler s birthday party.

I could add at least half a dozen more items to this... like not including a subject line, not answering a pointed question in a response, forwarding dumb jokes (hello 1996!) or replying to an entire email list with information that only applies to one person.
